(EFFI) Efftec International Inc., why am I not able to pull up its chart? I could a few days ago.

It's an OTC PINK stock, so possibly no broker dealer is quoting them, so no data feed?

From the otcmarkets site:

"How does a company get quoted on OTCQX, OTCQB and OTC Pink?

To get quoted as a OTCQX, OTCQB and OTC Pink security, a company must find one broker-dealer willing to quote their stock on OTC Link® ATS. Only SEC-registered broker-dealers that are members of the Financial Industry Regulatory Authority (FINRA) can quote securities. "

There doesn't even seem to be an internet site for this company.
